A Study Evaluating the Safety, Tolerability, and Initial Efficacy of Recombinant Human Anti-cluster Differentiation Antigen 47 (CD47) Monoclonal Antibody Injection (IBI188) in Patients With Advanced Malignant Tumors and Lymphomas

"The study is composed of two stages: Part 1 Accelerated Titration Phase and Part 2 Dose Escalation Phase with initial fixed priming dose.~The starting dose for part 1 is 0.1 mg/kg QW, followed by 2 dose cohorts (0.3 mg/kg QW and 1 mg/kg QW). Duration of dose limiting toxicity (DLT) observation is 28 days.~Part 2 will have 4 dose cohorts(3mg/kg QW、10mg/kg QW、20mg/kg QW and 30mg/kg QW). Conventional 3+3 Dose Escalation will be adopted. DLT observation period is 28 days."
